Yup, that's pretty much it, and one of the reasons I intensely dislike 'the beautiful game.'
I don't know why people take it so seriously, but there are studies (ah, the ubiquitous 'studies' again) which show heightened emotional involvement within sporting events. I think watching sports can bring a level of drama to those who are unable to experience it in their own lives and the passion invariably spills over. I don't understand it myself, but then I attend a class where I (try not to) get hit on a weekly basis so who am I to judge?
A friend of mine did try to explain to me the reasoning behind the love of the game and made a fairly good job of it, but I think it escapes me because it's not a logical, thoughtful involvement, but rather an emotional one. Reason, therefore, has little to do with it. Sadly, this last can be applied to a lot of UK society these days. Good grief, I sound like a whinging old git.
Is the film any good, by the by?
War. It's fan-tastic!
